Lipid bilayers are the basic structural components of all living systems, forming the membranes of cells, sub-cellular organelles, and extracellular vesicles. A class of man-made lipidic vesicles called multilobed magnetic liposomes (MMLs) is reported in this work; these MMLs possess a previously unattained combination of features owing to their unique multilobe structure and composition. MMLs consist of a central cluster of lipid-coated magnetic iron oxide nanoparticles that lend them a magnetophoretic velocity comparable to the most efficient living microswimmers. Multiple liposome-like lobes protrude from the central region; these can incorporate both water-soluble and lipid-soluble molecular payloads at high carrying capacity and exchange the incorporated substances with the membranes of both artificial and live cells by the contact diffusion mechanism. The size of MMLs is controllable in the range of 200-800 nm. Their functionality is demonstrated by completing a model mission where MMLs are remotely controlled to collect, transport, and deliver a cargo to live cells.

A 14-year-old spayed female Miniature Pinscher presented with tongue curling, dysphagia, hypersalivation, and sublingual gland swelling. Comprehensive evaluation, including neurologic and musculoskeletal examinations, blood work, and urinalysis, revealed no abnormalities other than tongue-related signs. Magnetic resonance imaging (MRI) revealed a multilobed cystic structure in the occipito-atlanto-axial joint, compressing the right hypoglossal canal.

Article Synopsis
- Chordoma is a rare cancer originating from notochordal tissue, mainly affecting the spine and often spreading to sites like lungs and bones.
- A case study describes a 52-year-old woman with sacral chordoma who developed a vascular liver mass, which was surgically removed but later recurred with additional metastases.
- This is the first recorded instance of recurrent chordoma specifically involving the liver along with metastases to other areas.

A 66-year-old male patient in follow-up in the urology department for a non-muscle-invasive bladder cancer was detected by ultrasound to have absence of the left kidney and a cystic, multilobed image at the location of the seminal vesicle. Magnetic resonance imaging reveals left renal agenesis and the existence of multiple cysts in the ipsilateral seminal vesicle that reaches a size of 6.9 × 3.

The cystic dilation of ventriculus terminalis (CDVT) is a rare anatomical variant in adulthood. In this report we describe a new case of an adult with multilobed CDVT, causing low-back pain and subjective disturbances in walking. A myelotomy with fenestration of the cyst was performed with a good clinical and radiological outcome.
